Hello Sohail and welcome to the Community!

Thank you for sending over your error log. The main item I would focus on would be the 401 API response you received. This response is normally associated with permissions/access. Meaning the account or token you’re using does not have access to the issue you're attempting to retrieve. Things to check for to ensure you’re able to GET data via the API:

Ensure the account/token used has permission to the project and may view issues
Ensure the credentials are correct
Ensure CAPTCHA has not been triggered for the user.

If you confirm the above and you’re still receiving a 401 response, please let us know the method/verb you’re attempting along with the endpoint you’re wanting to communicate with.

Regards,
Stephen Sifers

Hi Stephen,

I am also facing error 401.

I can create a ticket/issue via browser.

There is no CAPTCHA enabled when logged-in through browser.

I am using java api to connect to JIRA services to create issues. The URL being used is https://assurestart.atlassian.net/

The sample code is as below:

URI uri = new URI(property.getProperty("jira.url"));
final JiraRestClient jiraRestClient = new AsynchronousJiraRestClientFactory()
.createWithBasicHttpAuthentication(uri, property.getProperty("jira.username"),
property.getProperty("jira.password"));
jiraRestClient.getProjectClient().getProject("TA");
Promise<Project> projects = jiraRestClient.getProjectClient().getProject("HS");
System.out.println("Project name "+jiraRestClient.getProjectClient().getProject("TA").get().getName());

What I have observed is this code works intermittently. I remember it was working till mid of last week and it suddenly started throwing this error. The behaviour is really unpredictable. It may work for some days and then may not work again for a few days.

Hello Amol and welcome to the Community!

Without seeing the 401 response, which is most likely unauthorized, it would be difficult to fully understand the error you're seeing. With this said, ensure you're using Username and API Token for authentication. Do not use your password in this case.

Further information on tokens may be found at API tokens.

Issue resolved.

Thanks for taking time and respond, Stephen. I created API Token and tried with it and it magically worked.

Thanks for your help
